If checked, the application will remember what is the active workbench for each tab independently. This way, the active workbench will be automatically restored when changing tab in the multiple-document interface (MDI) view.

Use OpenGL Vertex Buffer Object

If checked, Vertex Buffer Objects (VBO) will be used. A VBO is an OpenGL feature that provides methods for uploading vertex data (position, normal vector, color, etc.) to the graphics card. VBOs offer substantial performance gains because the data resides in the graphics memory rather than the system memory and so it can be rendered directly by GPU. For more background info see this webpage.

One pass (default), rendering is done in one pass. For non-solid objects like faces or meshes this can lead to artifacts. This image shows such an artifact (black triangle) and that the type Backface pass avoids this.

Backface pass, has only an effect for non-solid objects. They are then rendered in two passes: Back-facing polygons are rendered in the first pass and the front-facing in the second pass.

Marker size

Selection of the size of vertices (points) in the Sketcher workbench. The clickable area of points can be additionally enlarged by increasing Pick radius (on Colors tab).

Eye to eye distance for stereo modes

Specification of the eye-to-eye distance used for stereo projections. The specified value is a factor that will be multiplied with the bounding box size of the 3D object that is currently displayed.

Backlight color

If checked, backlight is enabled with the defined color. Backlight is used for rendering back sides of faces (usually, you don't see them in solids, unless you slice one with a clipping plane, or if the faces aren't oriented correctly). It is only active for objects whose Lighting property (on View tab) is set to "One side". If disabled, back sides of faces of objects in "One side" lighting mode will be black.

The related Intensity setting specifies the intensity of the backlight.

Navigazione

This tab is always available, and controls the behavior of the navigation tools.

In the Navigation tab you can specify the following:

Name

Description

Navigation cube

If checked, the navigation cube will always be shown. Related Steps by turn defines how many steps (notches) will be applied when using the Navigation cube rotation arrows. Related Corner defines where the Navigation cube is displayed on the screen when creating/opening a document

Selection of the rotation orbit style. When viewing a part in the x-y plane an being in the rotation mode of the 3D navigation, the difference is: If Trackball is selected, moving the mouse horizontally will rotate the part around the y-axis, if Turntable is selected the part will be rotated around the z-axis.

New Document Camera Orientation

Selection of the camera orientation for new documents

New Document Scale

Affects the initial "zoom level" of camera for new documents. The value you set is the diameter of a sphere that fits in 3D view. Default is 100 mm, convenient for objects like boxes for Arduino. It also sets initial size of origin features (base planes in a new PartDesign Body).

Enable animation

If checked, rotations can be animated. If for example the 3D Navigation set CAD is used and the mouse is moved while the scroll wheel and the right mouse button is pressed, parts are rotated. If one keeps the mouse moving while releasing e.g. the right mouse button, the rotation will continue as animation. To end the animation left-click with the mouse.

Zoom at cursor

If checked, zoom operations will be performed at the position of the mouse pointer. Otherwise zoom operations will be performed at the center of the current view. The Zoom step defines how much will be zoomed. A zoom step of '1' means a factor of 7.5 for every zoom step.

Invert zoom

If checked, the direction of zoom operations will be inverted.

Disable touchscreen tilt gesture

If checked, the tilting gesture will be disabled for pinch-zooming (two-finger zooming). This only affects the 3D Navigation set Gesture.

Rotate at cursor

If checked, rotations in 3D will use the current cursor position as center for the rotation. Otherwise always the center of the screen will be used.

Colori

Questa scheda è sempre disponibile.

In the Colors tab you can specify the following:

Name

Description

Enable preselection highlighting

If checked, preselection is turned on and will be highlighted by the specified color. Preselection means that for example edges in parts will be highlighted while hovering with the mouse over them to indicate that they can be selected.

Enable selection highlighting

If checked, selection highlighting is turned on and the specified color will be used for it

Pick radius

Sets the area for picking elements in 3D view. Larger value makes it easier to pick things, but can make some small features impossible to select.

Simple color

If selected, the background for parts will have the selected color

Color gradient

If selected, the background for parts will have a vertical color gradient. The first color is the color at the top of the background, the second one the color at the bottom.

Middle color

Is only enabled if Color gradient is selected. If checked, the color gradient will get the selected color as middle color.

Object being edited

Selection of the background color for objects in the tree view that are currently edited

Active container

Selection of the background color for active containers in the tree view. For example if there are several parts in the tree view and one part is toggled as active body, it will get the selected background color in the tree view.

If checked, the bottom side of the surface will be rendered the same way than the top side. If not checked, it depends on the option Backlight color; either the backlight color will be used or black.

Text color

Text color for document annotations. There is currently no dialog to add annotations to documents. Annotations can only be added using the Python console with this command:

obj=App.ActiveDocument.addObject("App::Annotation", "Label")

This console is shown using the menu View → Panels → Python console.

Mesh view

This tab is only shown if you are in the Mesh Workbench or if you have been in this workbench before.

In the Mesh view tab you can specify the following:

Name

Description

Default mesh color

Selection of the default color for new meshes

Default line color

Selection of the default line color for new meshes

Mesh transparency

Specification of the default mesh transparency for new meshes

Line transparency

Specification of the default line transparency for new meshes

Two-side rendering

If checked, the bottom side of the surface will be rendered the same way than the top side. If not checked, it depends on the option Enable backlight color (see section 3D view). Either the backlight color will be used or black.

Show bounding-box for highlighted or selected meshes

If checked, a yellow bounding box will be displayed for highlighted or selected meshes.
